Computer Programming is a trade. Computer Science is a dicipline, a study, and an intellectual pursuit. A programmer who appreciates and understands the science behind effective programming will write algorithmically efficient code when appropriate. And if he has a foot firmly planted in reality, he won't waste a lot of time devising the perfect algorithm when the objective isn't execution efficiency so much as getting it up and running soon. Fortunately for us, CPAN has a plethora of modules written by Computer Science enthusiasts, that can be applied to the needs of the Computer Programming trade.
